A 100 percent commission brokerage describes what it provides beyond the split with a slide. Its fee schedule describes it with a ledger. eXp itemizes a $25 broker review fee per file. Real itemizes $40 for compliance and broker review, or $50 for transactions created on or after September 1, per Real’s own agent support center. Fathom’s published EDGE plan carries a $350 minimum transaction fee, with no separately itemized review line. The support a 100 percent brokerage owes its agents is already itemized, line by line, on the document its agents sign.
The belief worth testing is that a flat-fee model cannot afford support. The fee schedule says the opposite: the support is priced, the fees are collected, and on the biggest platforms those fees are already funding it.
Why it matters: for the broker-owner of a flat-fee shop, every line on that schedule is a promise with an operations bill behind it. Real reported $165.7 million of gross profit on 185,314 transactions in FY2025, or $894 per transaction, and that number funds everything: review, onboarding, technology, the person who answers the phone. The margin question is not whether to support agents. It is which lines to staff and which to buy per file.
The ledger has two cost shapes, and they behave differently as you recruit. Per-file purchases move with revenue: a reviewed file, a coordinated closing, an MLS entry each cost something only when a transaction exists to pay for it. Headcount moves in steps: a reviewer, an onboarder, a marketing hire each arrive as a full salary. BLS puts the median wage for the relevant back-office role at $47,450, roughly $69,100 fully loaded once benefits are added at the ECEC ratio. Each of those hires is either underused or overwhelmed, rarely neither. A brokerage recruiting successfully rides the step function up; a brokerage buying per file rides the revenue line. The gap between those two curves is where flat-fee margins go to die. We have watched that gap close from the inside: when Keith ran operations at HomeCity, a $500 million-a-year brokerage in Austin and Dallas, moving the back office off payroll took net margin from roughly 3% to over 25%.
Run the ledger against the platform arithmetic. Across eXp, Real and Fathom, published FY2025 figures work out to 5.18 transaction sides per agent per year. A hundred-agent flat-fee brokerage at that rate produces around 520 files a year, roughly 43 a month. The review line alone, at the platforms’ own $25 to $50 per file, collects between $13,000 and $26,000 a year against that volume. Whether that funds the work depends entirely on whether the work is bought per file or staffed as a salary that also runs onboarding and marketing, which at most independents it is. That is the line that breaks first, because it is the only one where the money already arrives per file and the cost still arrives per person.
What to watch, and the honest limits: the per-file fees are read from Real’s own support center and published summaries of eXp’s and Fathom’s schedules; independents structure these differently and many fold review into one transaction fee. The 5.18 sides figure is a platform mean from three public companies’ filings, while NAR’s 2026 Member Profile puts the typical REALTOR at nine sides, a survey median against a platform mean, not like-for-like. Fully loaded labor cost varies by market; the BLS-derived figure is a national anchor, not a quote.
The test to run: the problem at a 100 percent brokerage is the shape of the cost, not the level of support. Lines that collect per file and pay per person break exactly when recruiting works. The ledger test takes an afternoon: list every support promise on your fee schedule, mark which are staffed and which are bought per file, and ask of each staffed line what happens at fifty more agents. The ones with no good answer are the ones to move to a per-file basis. That is the argument behind brokerage-paid coordination, and the arithmetic behind the recruiting promise and the staffing ratio.

Frequently Asked Questions
What should a 100% commission brokerage provide its agents beyond the split?
What its own fee schedule already itemizes: file review, transaction support, onboarding, and the systems behind them. The published platforms price broker review at $25 to $50 per file. The question for a broker-owner is not whether to provide support but whether each line is staffed as headcount or bought per file, because the two cost shapes behave differently as agent count grows.
How do 100% commission brokerages afford support on thin margins?
By matching cost shape to revenue shape. Per-file support costs move with transactions, the same way flat-fee revenue does. Support staffed as salaries moves in steps and separates from revenue exactly when recruiting succeeds. The platforms’ own schedules show the support lines collected per file; the margin question is whether the work behind them is paid for the same way.
What does the broker review fee cover?
On published schedules it is the per-file charge for the brokerage’s compliance review of the transaction file: the check that the file is complete, correctly executed, and meets state requirements before the commission pays. eXp publishes $25 per file; Real publishes $40, rising to $50 on September 1, per its own agent support center.
